Description
Die Erfindung bezieht sich auf ein Kegelrollenlager nach dem Oberbegriff des Anspruchs 1.The invention relates to a tapered roller bearing according to the preamble of claim 1.
Kegelrollenlager besitzen üblicherweise einen Innen ring, der beidseitig Borde zur Führung und Halterung der Rollen besitzt. Die Montage der Rollen zusammen mit dem Käfig erfolgt dadurch, daß diese Teile im zusammengebauten Zustand über den kleinen Bord geschoben werden, bis die Rollen hinter diesem radial einschnappen. Dies ist dadurch möglich, daß entweder das Taschenspiel der Rollen sehr groß gehalten wird, so daß diese radial ausweichen können, oder daß der kleine Bord sehr niedrig ausgeführt wird. Beides sind Maßnahmen, die wesentliche Nachteile besitzen. Im ersteren Fall erfolgt nämlich keine genaue Füh rung und Halterung der Rollen im Lager. Im zweiten Fall besteht die Gefahr, daß zumindest einzelne Rollen herausfallen, selbst wenn in aufwendiger Weise eine hohe Genauigkeit der Teile eingehalten wird.Tapered roller bearings usually have an inside ring, the double-sided shelves for guidance and mounting who has roles. Assembling the rollers together with the cage in that these parts in assembled condition over the small board be pushed until the rollers are radial behind this snap in. This is possible because either the role play of the roles is kept very large, so that they can dodge radially, or that the small board is running very low. Both are measures that have significant disadvantages. In the former case, there is no precise guidance Roles in the warehouse. In the second Case there is a risk that at least some Rolls fall out, even if in more elaborate A high degree of accuracy of the parts was observed becomes.
Eine weitere Möglichkeit der Rollenmontage besteht noch darin, daß nach dem Einbau der Rollen auf den Innenring bestimmte Käfigabschnitte zu Haltenasen verformt werden. In diesem Falle kann zwar ein höherer Bord verwendet werden, es sind aber nach trägliche, zusätzliche und aufwendige Maßnahmen erforderlich.There is another possibility of reel assembly still in that after installing the rollers on the Inner ring certain cage sections to hold lugs be deformed. In this case, a higher board are used, but are after inert, additional and complex measures required.
Es ist daher Aufgabe der Erfindung, ein Kegelrollen lager nach dem Oberbegriff des Anspruchs 1 so weiter zu verbessern, daß die obengenannten Nachteile nicht auftreten und sich mit einfachen Mitteln eine si chere Halterung des Rollensatzes auf dem Innenring bei gleichzeitig genauer Führung der Rollen ergibt, ohne daß zusätzliche plastische Verformungen am Käfig nach dem Zusammenbau erforderlich werden.It is therefore an object of the invention to provide a tapered roller camp according to the preamble of claim 1 so on to improve that the above disadvantages are not occur and a si with simple means Chere bracket of the roller set on the inner ring results in precise guidance of the roles, without additional plastic deformation on Cage may be required after assembly.
Die Lösung dieser Aufgabe erfolgt durch die kenn zeichnenden Merkmale des Anspruchs 1. Anspruch 2 enthält eine bevorzugte Ausführung.This problem is solved by the kenn Distinguishing features of claim 1. Claim 2 contains a preferred embodiment.
Eine sichere Halterung der Rollen hinter dem kleinen Bord wird dadurch erreicht, daß im Bereich der Stege Vorsprünge vorgesehen werden, die hinter den kleinen Bord eingeschnappt sind. Diese und die Bordhöhe können deshalb groß gestaltet werden, weil der kleine Seitenring aus etwa radial gerichteten Wellen besteht, die die Elastizität dieses Käfigteils wesentlich erhöht und damit das beim Montieren erforderliche Aufweiten des Seitenrings begünstigt. Trotz hoher Vorsprünge bzw. hohem Bord besteht daher keine Gefahr, daß der kleine Seitenring beim Mon tieren des Käfigs in den Innenring beschädigt oder zerstört wird. Auch die Gefahr der Beschädigung der Rollen wird wesentlich herabgesetzt, da diese kräf tefrei über den Bord geführt werden. Die Aufweit kräfte des kleinen Käfigseitenrings belasten bei der Montage nämlich nur die Käfigvorsprünge und den Innenringbord. Außerdem ist keine Nacharbeit am Käfig nötig, um eine Baueinheit zu erreichen. A secure bracket for the rollers behind the small one Board is achieved in that in the area of the webs Projections are provided behind the small ones Board are snapped. This and the board height can be made large because the small side ring made of roughly radial shafts consists of the elasticity of this cage part significantly increased and thus during assembly favors required expansion of the side ring. Despite high protrusions or high board there is therefore no risk that the small side ring in Mon animals of the cage in the inner ring or damaged gets destroyed. Also the risk of damaging the Rolling is significantly reduced as this is strong be carried over the board free of tea. The expansion forces of the small cage side ring put a strain on the Installation namely only the cage projections and the Inner ring rim. In addition, there is no rework on Cage needed to reach a unit.
Dadurch, daß nach einer weiteren Ausgestaltung die Wellenberge zwischen den Stegen liegen, ist ein leichtes elastisches Aufbiegen der Stege nach außen möglich und der kleine Bord kann relativ hoch ausge führt werden, ohne daß es zu einer Berührung mit dem Käfig kommt.The fact that according to a further embodiment Mountains of waves between the webs is a slightly elastic bending of the webs outwards possible and the small board can be made relatively high lead without being in contact with the Cage is coming.
Aus der DE-AS 16 25 643 ist zwar ein Käfig für Kegelrollenlager bekannt, bei dem der kleine Seiten ring radiale Wellen besitzt, hier erfolgt die Ver formung nur zur Bildung einer kegeligen Form des Käfigs. Außerdem sind keine Haltevorsprünge vorge sehen.From DE-AS 16 25 643 is a cage for Tapered roller bearings known in which the small sides ring has radial waves, here the Ver forming only to form a conical shape of the Cage. In addition, no holding projections are featured see.
Die Erfindung wird mit Hilfe von zwei Figuren näher erläutert.The invention will be elucidated with the aid of two figures explained.
Fig. 1 zeigt einen Teilquerschnitt durch ein erfin dungsgemäßes Kegelrollenlager. Fig. 1 shows a partial cross section through an inventive tapered roller bearing.
Fig. 2 zeigt einen Teilausschnitt des Kegelrollen lagers nach Fig. 1 in axialer Draufsicht auf den kleinen Seitenring. Fig. 2 shows a partial section of the tapered roller bearing according to Fig. 1 in an axial plan view of the small side ring.
Gemäß Fig. 1 besteht das Kegelrollenlager aus einem Außenring 1, den Rollen 2, die von einem Fensterkä fig 3 in Abstand gehalten werden, und dem Innenring 4. Der Innenring 4 besitzt einen großen Bord 5 zur axialen Führung der Rollen 2 im Betrieb. Der kleine Bord 6 des lnnenrings 4 dient als Haltebord. Damit wird erreicht, daß der Rollensatz bestehend aus den Rollen 2 und dem Käfig 3 im nicht montierten Zustand mit dem Innenring 4 eine Baueinheit bildet. Referring to FIG. 1, the tapered roller bearing of an outer ring 1, the rollers 2 are held by a Fensterkä fig 3 in distance, and the inner ring 4. The inner ring 4 has a large rim 5 for axially guiding the rollers 2 during operation. The small board 6 of the inner ring 4 serves as a holding board. This ensures that the set of rollers consisting of the rollers 2 and the cage 3 forms a structural unit with the inner ring 4 in the unassembled state.
Aus diesem Grunde besitzt der Käfig 3 im Bereich der Stege 7 radiale Vorsprünge 8, die mit ihrer Spitze 8′ so hinter den Bord 6 greifen, daß sich eine sichere axiale Fixierung ohne Toleranzempfindlich keit ergibt. Das Aufweiten des Durchmessers dieser Vorsprünge 8 beim Gleiten der Rollen 2 über den Bord 6 wird dadurch wesentlich erleichtert, daß der kleine Seitenring 9 des Käfigs 3, wie insbesondere Fig. 2 zeigt, aus etwa radial gerichteten Wellen 10 besteht.For this reason, the cage 3 in the area of the webs 7 has radial projections 8 which engage with their tip 8 'behind the rim 6 so that there is a secure axial fixation without tolerance-sensitive speed. The widening of the diameter of these projections 8 when the rollers 2 slide over the rim 6 is made considerably easier in that the small side ring 9 of the cage 3 , as shown in particular in FIG. 2, consists of approximately radially directed shafts 10 .
Die dadurch erreichte höhere Elastizität bewirkt nämlich eine bessere Verformbarkeit des Seitenrings 9, ohne daß es zu Beschädigungen derselben bzw. der Rollen 2 kommt. Die Wellenberge 10′ sind im Bereich zwischen den Taschen 7 nach außen gerichtet. Damit wird verhindert, daß sie mit den kleinen Bord 6 in Berührung kommen und verschleißen.The higher elasticity achieved thereby causes a better deformability of the side ring 9 without causing damage to the same or the rollers 2 . The wave crests 10 'are directed in the area between the pockets 7 to the outside. This prevents them from coming into contact with the small board 6 and wearing out.
